- Properly add priority support. This is accomplished by rearranging the code
so that the bio module really does all of the i/o and allocators are just
responsible for making storage available.
- Add uuid support to make identifying devices reliable even if probing is
inconsistent. This also puts us one step closer to being able to get TuxOnIce
going on Debian via a simple apt-get install and reboot.
